# Onluyen vs OLM

The clearest difference is rating: Onluyen at 2.9 against OLM's 2.1. Onluyen also leads on ratings volume (218 vs 11). OLM's advantage is monetization model (free vs free with in-app purchases). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Onluyen sells 5 in-app purchases, starting at $4.49 per month and OLM sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Onluyen holds the better App Store score, 2.9 against 2.1. That said, the two scores are not equally well evidenced: Onluyen has 218 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 19% of Onluyen's written reviews are positive against 25% of OLM's, so the app with the better star average is not the one people write more warmly about.

Onluyen ships an update every 11 days, OLM weekly. The most recent releases landed on October 14, 2026 and October 7, 2026 respectively.
